Driving down a quiet street on a summer day with the car windows down, you see a convertible approaching from the opposite direc
1 answer:
Answer:
Explanation:
The ratio of apparent frequency and real frequency is 1.06 . Let v be their velocities . According to Doppler formula for source of sound and observer
approaching each other , the formula is as follows
n = n₀ ( V+v ) / (V-v )
Here V is velocity of sound which is 340 m /s
n / n₀ = ( V+v ) / (V-v )
1.08 =
360.4 - 1.06 v = 340 +v
v = 9.9 m /s.

<em>An electron has the same amount of energy in all orbitals is not true</em>
In an atom there are levels of energy in the skin and sub skin.
- This energy level is expressed in the form of electron configurations.
Writing electron configurations starts from the lowest to the highest sub-shell energy level.
So electrons that occupy the orbitals in the lowest sub-skin have the lowest energy level
- In the principle of Pauli's prohibition it was stated that there are no two electrons in one atom that can have the same four quantum numbers.
So suppose that there are two electrons occupying one orbital can have the same main quantum number (n), azimuth (l) and magnetic (m), then the last quantum number that is the quantum spin number (s) must be different.
So that the two electrons are different from just the quantum spin number, even though the other quantum numbers are the same.
So in one orbital only a maximum of 2 electrons is occupied, because if there is a third electron, this third electron will have the same quantum spin number as the previous electron
- The electron cloud is a visual representation of the location of electrons in an atom.
Orbital is the place around the nucleus where electrons may be found
Electron clouds show the state of electrons in their orbitals
So electron clouds can show the condition of all orbitals in an atom
The lowest energy level of an electron occupies a sub-skin of 1s which has only one orbital
Charging electrons in the sub skin uses the following sequence:
1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4p⁶, 5s², 4d¹⁰, 5p⁶, 6s², etc.

Answer:
Explanation:
From Newton's second law,
where is the force,
is the mass and
is the acceleration.
From Hooke's law,
where is the spring constant and
is the displacement function measured from the origin. The negative sign indicates the force acts in opposite direction to the displacement. In fact, it is a restoring force; it acts to return the spring to its original undisturbed position.
Since both forces are the same,
The implication of this is that the acceleration is proportional to the displacement but opposite to it. That last statement is the definition of a simple harmonic motion which this is.
The ratio is a constant except in situations where the mass is varying (say, the mass on the spring is a decaying material).
